SPECIFICATION forming part of Letters Patent N 0. 729,096, dated May 26, 1903. Application filed March 3, 1902. Serial No. 96,424. (No model.)

To aZZ whont it may concern.-

Be it known that I, FRANCIS J. RABBETH, a citizen of the United States, residing at Redlands, in the county of San Bernardino and State of California, have invented an Improvement in Fliers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Heretoforefliers used in spinning and twisting machines have commonly been connected to the upper end of the spindle by a screwthread and in case of change of direction of rotation of thespindle is loosened thereon. So, also, the fliers have usually presented two solid legs bent or provided at their ends with curls to form eyes in either of which the yarn being spun or twisted is placed and through i which the yarn passes to the usual bobbin,

spool, or other device on which the yarn is to be Wound. These usual fliers are of considerable weight and are liable to be bent out of shape due to centrifugal action when the spindle carrying the flier is rotated at high speed, and, in fact, the speed at whicha spindle and flier having the solid legs may be run is limited by the weight of the legs and the tendency of the flier to expand due to centrifugal action.

I have aimed to provide a flier that is automatically clamped adhesively to the upper end of the spindle, and the faster the speed of the spindle and flier the tighter the fit and more secure the clamping of the flier to the tapered end of the spindle. I have also provided a flier havinga minimum of Weight in its arms, and I have made the arms of tubes that will stand a maximum of strain due to centrifugal action of the flier without springing or bending.

In my invention the expansion of the flier due to centrifugal action is made available to spring the yoke or head of the flier and enable the split hub thereof to be contracted and fit more snugly the tapered upper end of the spindle, causing the flier to be driven adhesively by the spindle.

Figure 1 in side elevation represents a flier embodying my invention in one of the best forms now known tome, the flier being sustained by a spindle only partially shown. Fig. 2 is a top View of the flier alone. Fig. 3

isa view like Fig. 1, but With the flier in sec tion. Fig. 4 is a section of the flier in the line m, Fig. 1; and Fig. 5 is a detail showing the hub of the flier and part of the spindle.

The spindle A is andmay be of any usual shape or character, it having its upper end tapered, as at ct. The degree of the taper of the upper end of the spindle may vary as necessity may demand.

The flier B is composed of a yoke or head I), having a huh I), that may be split in any suitable manner, as at 11 the split extending, preferably, from the end of the hub to and preferably crossing more or less the longitudinal center of said head in the direction of its length,'leaving a portion of metal, as at N, at each side of the head that may spring more or less under centrifugal action when the spindle and flier are rotated rapidly, the spring of the head causing the inner walls of the hub to approach each other and contract the tapered opening made through the hub that said hub may be clamped closely to the tapered upper end of the spindle and so clamp the flier adhesively to the spindle that the spindle may move the flier, and it is immaterial whether the spindle and flier are rotated to the right or left, as the centrifugal clamping acts in either direction of rotation of the spindle.

To increase the tendency of the hub to yield and contract due to centrifugal action of the flier, I have shown the head as provided at right angles to the slot 6 and at the lower end thereof with cuts 0, that maybe made by a circular cutter acting against the sides of the head, the cut intersecting the slots 11*. The head at each side of the hub is shown as hollow; but if it were made solid my invention as regards the hub and the automatic clamping of the flier on the spindle would not be departed from.

The legs b of the flier are composed of steel tubes, preferably tapered inthe direction of their length. The upper ends of the legs are shown as inserted in holes in the ends of the head and the lower ends of the legs receive each a suitable guide-eye (2, shown as composed of wire.

In using the flier it is only necessary to set the hub of the flier on the tapered end of the spindle and slightly crowd the flier down onto the spindle to a firm seat. As soon as the spindle and flier are started the centrifugal action of the legs causes the head to be sprung slightly, and thus close the hub firmly onto the spindle, thus holding the flier securely in position on the spindle, so that the spindle drives the flier by an adhesive fit.

In some instances it may be deemed desirable to provide means whereby the flier if struck by any upwardly-delivered blow will not be detached from the spindle. To insure the retention of the flier on the spindle, I have inserted a pinfin the top of thespindle. The length of the pin, however, will preferably be less than the diameter of the tapered opening in the lower end of the hub, so that the pin may enter the opening freely, the ends of the pin entering the slots b and when the hub is fully seated on the tapered end of the spindle the pins will pass out of the slots 19 and stand substantially opposite the outer end of the hub, so that by turning the flier slightly on the spindle the pin may abut a part of the hub out of the line of the slot. In some instances, however, this pin or locking device to retain the flier on the spindle will not be necessary.

This invention is not limited to the particular shape of the hub and head nor to the particular shape of the slot in the hub or the construction shown for the stop to prevent the accidental lifting of the flier from the spindle.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Thecombination with a spindle, of a flier having a contractible hub to engage said spindle and be contracted and held thereon by centrifugal action.

2. A flier having a split hub, the space in the hub being capable of being contracted as the flier is rotated rapidly.

3. A flier having a hub tapered at its interior, and split from its end downwardly into the head of the flier.

4. A flier having a tapered hub split from its ends downwardly into the head of the flier, and the head slotted to intersect the slots of the hub to thereby leave a portion of the flier that may yield under centrifugal action and enable the space in the hub to be contracted to grasp the spindle firmly and be revolved thereby.

5. A flier having a hub and head provided with tubular arms tapered and inserted in tapering holes in the head.

6. A flier having a hub and atubular head provided with tubular tapered arms and separate guide-eyes inserted in the ends of said tubular tapered arms.

7. A flier having a head provided with a split and contractible hub, and tubular arms extended from said head, said hub being contractible under centrifugal action of the arms.

8. A flier having a tubular head provided with a split hub, and tubular tapered arms extended through holes in and depending from said head.

9. A spindle, a flier having a contractible hub adapted to be clamped adhesively thereto due to centrifugal action, and means to prevent the accidental lifting of the flier from the spindle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANCIS J. RABBETH.
